WASHINGTON – Convicted FBI spy Robert Hanssen, who’s set to be sentenced to life in prison tomorrow, asked his best friend to drug and have sex with his wife, Bonnie, according to a new book.

Hanssen pal Jack Hoschouer confirmed the story, telling Time magazine that Hanssen asked him to secretly give the date-rape drug Rohypnol to Bonnie and then have sex with her. Hoschouer, a retired Army officer, said he refused.

“I have my faults, but I’m not a rapist,” he said. Hoschouer did go so far as to watch Hanssen and his wife having sex on a video monitor linked to a surveillance system that Hanssen set up in his bedroom. Hanssen’s drug-and-rape suggestion was published in Lawrence Schiller’s “novelization” of the story, “Into the Mirror: The Life of Master Spy Robert P. Hanssen.”

Hanssen is considered one of the most damaging spies in U.S. history, but prosecutors are recommending life in prison instead of death because he pleaded guilty and vowed to cooperate. Still, there are mixed reports of how cooperative he’s been.
